High Quality Content by WIKIPEDIA articles! VoIP User is a community driven and financed SIP based VoIP network. The projects aim is to introduce people to the concept of VoIP by allowing members to experiment with SIP and IAX2 devices.The VoIP User network was designed to operate within a community environment and therefore differs substantially from most other VoIP networks. The main highlighted difference being that users can call PSTN phone numbers through VoIP User's PSTN gateway without incurring any call charges. The way that VoIP User is funded is noteworthy: Calls into VoIP User?s numbers generate a small amount of per minute revenue (the ?termination charge?), and this money goes into a community account or ?pot?.

IP Phone
29,90 € *
ggf. zzgl. Versand

An IP phone uses Voice over IP technologies allowing telephone calls to be made over an IP network such as the internet instead of the ordinary PSTN system. Calls can traverse the Internet, or a private IP Network such as that of a company. The phones use control protocols such as Session Initiation Protocol, Skinny Client Control Protocol or one of various proprietary protocols such as that used by Skype. IP phones can be simple software-based Softphones or purpose-built hardware devices that appear much like an ordinary telephone or a cordless phone. Ordinary PSTN phones are used as IP phones with analog telephony adapters (ATA).It may have many features an analog phone doesn't support, such as e-mail-like IDs for contacts that may be easier to remember than names or phone numbers.

YATE Yet Another Telephony Engine
50,40 € *

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Yate is a telephony engine, a softswitch with PBX capabilities, originally created in 2004 by Paul Chitescu of NullTeam. It is released under a GNU General Public License with an exception for linking with OpenH323 and PWlib (licensed under MPL). Started as a free/open source softswitch for connecting PSTN with VoIP, support for other telephony technologies like conference, PBX, IVR has been added later on. During the years Yate has evolved into a Unified Communications server providing advanced integration with instant messaging, video and fax. Historically the basic function of Yate is the softswitch, connecting together call legs either to external devices or internal server resources. The logic for routing calls uses messages and can be implemented in configuration files, database queries or external programs. Call signalling is possible using PSTN protocols like ISDN or SS7, either directly attached over a TDM interface card (T1, E1, BRI), analog interface or by a remote Signaling gateway. A variety of VoIP protocols can be used without the need of special hardware: SIP, H.323, IAX2 or Jingle

Softswitch: Charging, Accounting and Billing
51,30 € *
ggf. zzgl. Versand

Softswitch is an innovative concept in the field of telecommunication and ICT, which creates new challenges and opportunities for the network operators, service providers and researchers. The migration from PSTN to NGN involves the convergence between PSTN and IP network that is a single network for voice, data and video. Softswitch performs all analysis functions, routes signalling messages and handles traffic data. So it requires an extension of existing charging collection mechanisms and billing system that is functionally intelligent and flexible, and provides fair policy towards end users. The book is designed to present the design principle and implementation concept of Softswitch. It also includes different convergence billing protocols and their interface challenges. In addition, the operational results at the end demonstrate the effectiveness of the Softswitch with billing interface. On the whole, the study has sought to explicate an integrated system for Charging, Accounting and Billing, which is capable of handling all the challenges and generating fair traffic bill.
